Patented Aug. 16, 1932 UNITED STATES PATENT: orrlcs ZANVIL c. LOEIBEL, or SHOREWOOD, wIsooNsIN, AssIGNon TO A. 0. SMITH oonronn- TION, or MI WAUKE WISCONSIN, A CORPORATION on NEW Yom;

WIlN'DOW CONSTRUCTION This invention relates to window construction and more particularly to means for securin window panes in place within a sash.

In the drawing wherein are illustrated several modifications of the present invention:

Figure 1 is a view ofa window frame having a glass pane secured therein;

Fig. 2 is "a cross sectional view taken'on the plane represented by the 'line 2"2'0f Fig. 1; and

Figs. 3 and 4 are similar views of modified forms of construction.

Referring now more particularly to the drawing, the sash 10 is composed'of a frame member 11 and a retaining strip 12, the latter being secured to the frame by means of the bolts 13. Disposed within the channel formed between the frame member'll and retaining strip 12, is a thin aluminum strip 14 of U-shaped cross section. The U shaped strip 14 is spaced. from the bottom of the channel in the sash by means of cork spacer blocks 15, two of which are ordinarily employed in each side of the frame.

Disposed within the channel shaped strip 14 is a pane of glass 16 which is spaced from the sides of the channel shaped strips by means of cork strips 17. The 'edge'of the glass is spaced from the bottom of the, channel shaped strips by means of resilient nondrying putty 18. The strip of putty 18 is formed by an extruding process in order that the same will be of uniform thickness along the entire sides of the frame.

The sides of the channel shaped'strip 14 are provided with a plurality of spaced proa.

J the entrance of moisture thereinto. Theputty 20' is also of the resilientnon-dryin'g kind. I However, since both the strips 14 and 17 are composed of non-erosive materials, the fillet 20 of putty need not be provided, since any moisture which may enter the channel formed in the frame wouldin no way cause deterioration; of these strips.

In assembling the, structure described, the retaining strips .12-are forced toward the frame member 11 to put the cork strips 17 u k under compression to form a tight joint be tweenthe glass and the frame and the retaining. strips are then secured in this .position to-maintain1 the".joint.- Y

The construction abovedescribed allows '0 for relative lateral movementbetween the frame member and the glass when the latter is subjected to lateralvpressure and alsoal lows for longitudinal movement of the glass with respect to. the framedue to relative 5 expansion betweenthe glass andzthe frame. The structure isiespecially designed to accommodate this longitudinal-movement between glass and aluminum which have a rela tively great difference of thermal coefficients of expansion, but it is equally well adapted to any two substanceshaving different coefficients of expansion. When, for example, a strong'wind is "blowing against the'pane of glass,- the glass will be forced in one direction and slightly further compress one of the cork strips 17, and also one of the putty fillets'20on the leeward side ofthe glass. Upon. abatement of this'wind pressure upon the glass'the putty and corkstripswill resume their original shape. 1 .During expansionor "contraction of the frame and glass there will be relative longitudinal movement of the two-only at the top and sides of the window. There will be no relative movement between the glass and the frameat the lower edge, since the. weight of :theglass always maintains the same seated within the channelshaped strip. The longitudinal movement of the glass 3 withinthe frame at the top and sides of the frame may cause a separationbfthe-glass from the putty fillets 20, but this separation would notallow any appreciable amountof .water to enter in between the glass and the W fillets at the sides and top of the window. Should water enter between the glass and fillets 20-it would jbevery dilficult for it to pass from the-channelto .the other side of I the glass. 1 In order to positively preclude i by Letters Patent is:

from that shown in Fig. 2 in thatthe U shaped metal strip" is in contact" with the glass, and the cork strips are interposed be tween the metal strip and the members 11 and 12 of the frame. Relative movement be tween the cork strips and the U shaped metal strips is prevented in a manner similar to thatdescribed: in connection with Fig. 2.

Fig. 4 difiers from Fig.1 in that it has additional cork strips 21 which are interposed between "the sides of-the' U shaped 'metal strip and the members ll and 12 of the frame. V

Although the: foregoing description is necessarily ofa detailed character in order to completely set: forth thepreferred enibodiments of the invention, it is to be undrsto'od that-the specific terminology "is not intended toibe restrictive or confining and it. isto be further understood that various rearrangements .of parts and modifications of structural detail may be resorted to. without departing from the scope or spirit of the invention as herein claimed.
